In a world first, they used two-dimensional (2D) materials, which are only an atom thick and retain their properties at that scale, unlike silicon, to develop a computer capable of simple operations.

To make the computer, the researchers used two different 2D materials: molybdenum disulfide for one type of transistor and tungsten diselenide for another. Image: Conceptual illustration of a ...
